Is My Calculation of NO2 Produced from N2O5 Decomposition Correct?

In summary, to solve a chemistry homework problem, one should carefully read and understand the problem, identify relevant concepts and equations, and plug in given values to arrive at an answer. If stuck, it is helpful to break the problem into smaller parts and seek help from resources. To check the answer, one can plug it back into the equation and use online calculators or ask for feedback. Calculators can be used, but it is important to make sure they are allowed and appropriate. To improve understanding, active participation, taking notes, asking questions, and seeking help can be beneficial.

2N2O5 heat-- 4NO2 + O2

1.618 g of O2 are produced, how much NO2 in grams are produced? I got 9.30 g NO2, is that right? I used 1 mol O2 = 32 g O2, and 1 mol NO2 = 46g NO2. I first converted g O2 to Mol O2 then used the balanced equation to convert from mol O2 to mol NO2, then converted to NO2 to grams. If anyone can tell me if I did this right I would greatly appreciate it.

I agree with both your final answer as well as your method used to obtain it.

Your calculations appear to be correct. It is important to use the molar ratios from the balanced equation to convert between moles of O2 and moles of NO2, and then use the molar mass of NO2 to convert from moles to grams. Double checking your calculations and using the correct units throughout the conversion process is always a good practice. Keep up the good work!
